Footwear cleat with cushioning
View Patent ↗A removable cleat for footwear. The cleat includes a disc with opposing faces. A shoe coupling element is attached to one face of the disc. The other disc face supports a cushioning layer. Traction elements are supported by the cushioning layer. When a user steps on a surface wearing a shoe outfitted with these cleats, the resilience of the cushioning layer at once both lessens the impact of the traction elements on the ground surface and lessens the reaction force on the user's foot transmitted through the shoe's outsole. The user's comfort is thereby enhanced.
1. A ground-engaging cleat for a shoe, comprising:
a base layer having a top surface and a bottom surface;
a cushioning layer having a top surface attached to the bottom surface of the base layer; and
a traction element layer having a top surface attached to the bottom surface of the cushioning layer, the traction element layer comprising a plurality of spokes projecting radially outwardly from a central axis of the cleat, each spoke having a traction element;
wherein the top surface of the cushioning layer defines at least one cavity associated with each spoke.
2. A ground-engaging cleat according to claim 1 wherein the cleat includes a shoe attachment element.
3. A ground-engaging cleat according to claim 2 wherein the base layer of the cleat includes the shoe attachment element.
4. A ground-engaging cleat according to claim 1 wherein the durometer of the traction element layer is not less than 80 on the Shore A scale.
5. A ground-engaging cleat according to claim 1 wherein a thickness of the cushioning layer at the periphery of the cleat is larger than a thickness at the center of the cleat.
6. A ground-engaging cleat according to claim 1 wherein a slot or groove is radially disposed near the periphery of the cushioning layer.
7. A ground-engaging cleat according to claim 1 wherein the at least one cavity has an inner wall and an outer wall, and wherein a thickness of the outer wall is thinner than a thickness of the inner wall.
8. A ground-engaging cleat according to claim 7 wherein at least a portion of the outer wall of the cushioning layer is configured to deflect upon pressure from the weight of a wearer.
9. A ground-engaging cleat for a shoe, comprising:
a base layer having a top surface and a bottom surface;
a cushioning layer having a top surface, at least a portion of the top surface being attached to at least a portion of the bottom surface of the base layer; and
a traction element layer having a top surface attached to at least a portion of the bottom surface of the cushioning layer;
wherein the top surface of the cushioning layer defines a cavity, and
a slot or groove is radially disposed near the periphery of the cushioning layer.
10. A ground-engaging cleat according to claim 9 wherein at least a portion of the outer wall of the cushioning layer is configured to deflect upon pressure from the weight of a wearer.
11. A ground-engaging cleat for a shoe, comprising:
a base layer having a top surface and a bottom surface;
a cushioning layer having a top surface attached to at least a portion of the bottom surface of the base layer; and
a traction element layer having a top surface attached to the bottom surface of the cushioning layer,
wherein the top surface of the cushioning layer defines a cavity, the cavity having an inner wall and an outer wall,
wherein a thickness of the outer wall is thinner than a thickness of the inner wall.
